It's not a P2, the picture is just named P2. Its just an ordinary pentium 1, the purple ceramic kind with the black cap. Pictures P1, P2, and P3 are all pictures of the same chip, the pentium 1.
Just for the record, there is no Pentium chip with purple ceramic and a black cap. Only either gold capped Pentium 1's were made, or just straight ceramic. The only black-capped Pentium-compatible processors I can think of off-hand would be the Cyrix variants.
